To aZZ whom it may concern.-

Be it known that I, HENRY N. HEMINGWAY, of Auburn, in the county ofOayuga, in the State of New York, have invented an Improvement inMachines for Manufacturing Button-Fasteners, of which thefollowingdescription, in connection with the accompanying drawings, is aspecification, like letters on the drawings representing like parts.

The object of this machine is to manufacture buttonfasteners such asdescribed in United States Patent No. 295,709, granted to W. H. WVood,to which reference may be had. In this my improved machine the wiretaken 1 from acoil by suitable feeding mechanism is fed past wirecutters or shears and across a die, where it is caught by a punch, andthe cutting mechanism then cuts off the wire of proper length toconstitute a blank for a fastener.

The punch is then moved forward to force the wire into the die to formits hook part, shank, and prong, anda wire-coiler then takes hold of thewire between the punch and die on one side and the cutting mechanism onthe other 2 5 side and winds the end of the wire blank about the punchto form the base of the fastener.

The particular features in which my invention consists will beespecially pointed outin 0 the following description, and designatedinthe claims.

Figure l is a top or plan view of a machine embodying my invention. Fig.2 is a diagram showing the blank in the different shapes assumed by it,and the completed fastener. Fig. 3 is a front elevation of Fig. 1, thereel being omitted and the driving-pulley being in section. Fig. 4 is asection of Fig. 3in the dotted line a: an -Fig. 5 is asection in thedotted line 00 00',- Fig. 6, a longitudinal section of the punch andwire-coiler removed, showing the grooves therein Fig. 7, deta'ilsin topview and section of the (lie enlarged; Fig. 8, details in end view andsection of the wire-coiler enlarged; Fig. 9, details of the punch; Fig.10, a side elevation of the movable memberof the shears or wire-cuttingmechanism; Fig. 11,- a top view of the stationary co-operating member ofthe shears or wire-cutting mechanism.

The base A has suitable uprights containing boxes to sustain thedifferent shafts and working parts, to be described. The main shaft Bhas fast upon it a pulley, B, a gear,

0, and a pulley or wheel, E the latter having at one side of it teeth12, herein shown as three in number. These teeth engage the teeth of agear, cl, at one end of the lower feed-roller, D, having at its oppositeend a gear, (P, which engages a gear, cl, on the shaft of the upperfeed-roller, D, the said rollers constituting awire-feeding mechanism.These rollers, grooved annularly for the reception of the wire, andhaving their bearings in adjustable boxes, whereby the rollers areadapted to the diameter of the wire to being used, are movedintermittingly by the teeth I), brought at intervals into engagementwith the teeth of the wheel d, thus feeding forward a sufficient lengthof wire for the production of a fasten- 7o ing. The wire, after passingbeyond the feeding-rollers, is fed into a groove, 6, made in the movablemember 6 of the wirecutting mechanism, the lower member being marked aThe section, Fig. 5, showing the cutting mechanism is taken at one sideof the center line of the cutting member 6", as will be noticed byreference to the dotted section-line, Fig.

3. The groove 6 is preferably made annular,

so that the member 0 may be turned or adjusted about its center to bringinto operative position a new edge, to thus compensate for wear. Thelower member, 6", is made as a sleeve having, preferably, a head, asshown clearly in Fig. 5, by which to support it in the frame-work, thesaid head at its top or face having a cross-groove, 2, which intersectsthe central opening, 3, of the said sleeve,

as shown in Fig. 11. The movable cutter. member 6, extended through theopening 3 9o (see Fig. 5) of the sleeve, rests upon a spring. 6 whichnormally acts to keep the member 6 elevated, as in Fig. 5, so that thewire 20, taken from a suitable reel, may be fed by the rollers D D intoand through the grooves 2 and e, referred to, and the wire havingreachecLthe position indicated in 5, the said wire hav ing been fed pastthe opening 4 of the die g, the movable member 6 of the cutter isdepressed or forced down by the follower F, the 100 latter being throwndown quickly by the projection f on the main rotating shaft B, the

said projection striking against a toe, 6, 011 punch reaches the end ofits stroke in the die the follower. The die 9 has a tubular hub orprojection, (shown best in Fig. 7,) which is slotted or cut away, astherein shown at 5, to receive the wire, the latter being fed into position to stand diametrically across the dieopening 4. Just before thecutter member 6 is forced down to sever the wire located in its groove eand in the groove 2 of the member 0 the said wire, so laid and heldacross the said die-opening, is caught and held in place by the end ofthe punch h, to be described. The wire having been cut off to form ablank, ll, of sufficient length for the production-of a fastener, f, thepunch is further moved forward by its actuating devices, and is made'toforce a part of the said wire-blank into the die-opening 4,*thusfor1ningthe shank 8, (see Fig. 2,) leaving beyond it and in the groove at theright of the die-opening, Fig. 7, a portion 'of wireto form the point 7for the fastener, a portion of the wire of the blank between the punchand die on one side and the cutting mechanism on the other side beingthereafter coiled about the punch, as will be described, to formthe base14. (See'Fig. 2.) The punch h, made as a rod reduced at its front endand grooved at 9, (see Fig. 9,) has a collar, h, fastened to its rearend. (See Fig. 6.) This collar has two small holes or openings, whichreceive two pins, h fixed in a second collar or-sleeve, h havingspannerlike projections h, which are embraced by a notched part of thepunch-moving lever, [L5, pivoted at h on an ear, h and having a rolleror other stud, h which at the proper time is acted upon by'thecam-surface If of the pulley B. The camsurface I), when operative, movesthe punch forward to force the blank into the die-opening 4, and whenthe punch is to be withdrawn therefrom to permit the discharge of thefastener the cam or wiper h fast on the shaft B, becomes operative andstrikes the roller or other stud, h, also carried by the said lever If.The punch has only a movement of reciprocation, but the wire-coiler nthereon is rotated continuously in one direction. The wire-coiler a,made as a sleeve and receiving the punch within it, has at its front enda shoulder or projection, 12, about onehundred and eighty degrees inlength, and the rear end of the said wire-coiler, having a flange, 13,is extended through and takes its bearing in the sleeve k referred to,the said sleeve being chambered, as shown at 14, to receive the flange13 of the wire-coiler a, such construction enabling the punch to bereciprocated within the wire-coiler without carrying the latter with it,and also permitting the wire-coiler to be rotated continuously about thepunch.

The wire-coiler has splined upon it a gear, 01 which is driven by thegear 0. The gear a is restrained from lateral motion by the ends of thebearings n n for the wire-coiler.

During the first part of the forward movement of the punch by the leverIf the punch is moved through the wire-'coiler; but before the thecollar h meets the outer end of the wirecoiler, and it and the punch aremoved forward together until the face of the projection 12, near itsheel, acts upon the end of the wire at the right of the dieopening 4,and forces the same into the slot 5 of the hub 9, thus giving the properset and direction to the point 7 of the fastener. The punch havingforced the wire into the die, as stated, the end of the projection orshoulder 12 of the wirecoiler, in the rotation of the latter in thedirection of the arrow thereon, Fig. 8. strikes the portion of the blankat the left of the dieopening and coils the wire of the blank about thepunch, between the end of the wire-coiler and the end of the hub g ofthe die 9, the part of the blank so coiled forming the base 14 of thefastener, (see Fig. 2,) and then the wire-coiler and punch are retractedtogether by thelever hf until the punch is withdrawn from the die, andthereafter the punch is drawn back into the wire-coiler, thusdischarging the fastener from the punch, it falling therefrom,preferablyinto aspout, 15. (Shown by dotted lines, Fig. 1.) At thecommencement of the backward movement of the punch and wire-coiler thesaid parts are in the relation to each other shown in Figzti. The lever7L5, embracing the projections It of the sleeve 71- starts the punchbackward, and the wirecoiler moves with it, owing to the frictionbetween the two; but as soon as the spline 18, connected with thewire-coiler, meets the end of one of the bearings t at the side of thegear a the said wire-coiler is stopped, but the backward movement of thepunch by the lever h is continued until the punch is withdrawn orretracted into the wire-coiler far enough to effect the discharge of thefastener from the punch, the fastener dropping into a chute, asdescribed.

I do not desire to limit my invention to the exact form of wire feedingand cutting mechanism, and instead of the said parts I may use anywell-known equivalents; but in practice I prefer the particular partsherein shown. The groove 9 is made in but one side of the punch b, andin practice it falls opposite the recess 24 made in the hub g of the dieg opposite the groove 5. The wall of the said hub at this point forms arest for that part of the wire of the blank at the junction of thebase14 and shank 8. The hub g not being out through at 24 to the same depthas at 5 enables the bend between the base'and shank to be made in oneplane, and the bend between the point and shank to be made in anotherplane, so as to enable the point 7 to project laterally above the base.

The cutting mechanism, when severing the wire, cuts the same at aninclination, thus sharpening or bending the point 7.

I claim- 1. The die provided with the hub g, and the longitudinalreciprocating punch, in combination with a wire-coiling device having arotary movement to bend the wire into a coil to form the base of thefastener, as shown and described.

2. The die provided with the hub or pro- 5 jection g, slotted, as shown,in combination with the punch and concentric wire-coiler, and means tooperate the same, substantially as described.

3. The die and the punch and its connected 1o sleeve and collar, incombination with the wirecoiler having a head at one end and placedbetween the said sleeve and collar, substantially as described.

4. The cutter member eZprovided with a cen- 1-5 tral opening and across-groove, 2, combined with a reciprocating cutter member, 6, pro-HENRY N. HEMINGWAY.
